Also, E85 is awesome. People on the national DSM boards are making the same power on E85 that other people have made on 110 leaded. A guy with a 16g just put down 402 whp on E85 spiking over 30 psi and falling to 25 at redline. That's one of the highest 16g dyno numbers. I can't wait for the stuff to be made locally so I can convert my car to run on it. Race gas tune all the time- an extra 40-50 hp for free.
